I run cfl spiral bulbs. I use multiple lightbulbs on the top and sides of the plant (8 bulbs in a 2x2x3 box) (3 6700k, 4- 5000k , and 1-2700k )
for vegging.

However you gotta have the right spectrum. You know how light bulbs are labeled as "cool white or warm white". 5000-6700k which is the blue spectrum is important for vegetative growth. They are labeled "cool" for flowering you want the red spectrum which is 2700k or red labeled as warm.
